Description

TECHNICAL FIELD

[0001] The utility model belongs to distribution valve support technical field, especially relate to a ceramic filter distribution valve support. BACKGROUND

[0002] The ceramic filter distribution valve device includes distribution valve, distribution valve support, static friction circle, dynamic friction circle, filtrate pipeline and backwash pipeline etc.. The stainless steel plate in the distribution valve divides the distribution valve into three different areas: moisture absorption area, dry area and backwash area. The processed distribution valve is installed on the distribution valve support, and the static friction circle glued on the distribution valve and the dynamic friction circle glued on the drum shaft head or end flange are tightly attached through the spring, which plays a role of rotary sealing. The filtrate pipeline of the moisture absorption area and the dry area on the distribution valve is connected to the filtrate tank, and the backwash area is connected to the backwash pipeline. During production and operation, the filtrate pipe on the drum successively passes through the moisture absorption area, the dry area and the backwash area on the distribution valve with the rotation of the drum, and when the filtrate pipeline passes through the moisture absorption area, the ceramic filter plate connected to the filtrate pipeline starts to absorb slurry to make the minerals in the slurry adhere to the ceramic filter plate. When the filtrate pipeline turns through the dry area, the minerals adhered to the ceramic filter plate are continuously dehydrated and dried under the vacuum action of the filtrate tank, and before reaching the backwash area, the dried filter cake is scraped off from the ceramic filter plate under the action of the scraper. After the ceramic filter plate is scraped off the filter cake, when the filtrate pipeline rotates to the backwash area, the minerals adhered to the filter membrane on the surface of the filter plate are washed away under the pressure of the backwash water, so as to prolong the decay period of the filter plate.

[0003] Because the old distribution valve device support is fixedly installed on the rack from the lower side, and the distribution valve is fixed on the distribution valve support through two fixed ear plates, there is no fixed point on the upper and lower sides of the distribution valve support, and there is also no supporting point below the distribution valve. First, in the long-term operation process, due to the self-weight drop of the distribution valve, unilateral stress, eccentric stress, especially the old glue removal process required for replacing the friction circle each time, the distribution valve matching surface is easily worn, which leads to uneven matching surface, the coaxiality and parallelism deviation of the friction circle and the matching surface caused by the technical reasons of the installation personnel, it is difficult to adjust the coaxiality of the distribution valve and the drum through the installation mode of the two fixed ear plates and the fixed base of the distribution valve, which causes the step and unevenness of the friction circle side wear, destroys the parallelism of the friction circle, causes the compression spring to fail, leads to poor sealing of the dynamic and static friction circles, loses the vacuum degree, and causes the leakage of filtrate and acid liquid, which reduces the filtering efficiency of the ceramic filter, increases the moisture of the filter cake, and shortens the service life of the friction circle, which directly affects the production efficiency and economic benefits of the using unit, causes safety hazards, etc. Second, the old support does not have a support valve body device, and because the distribution valve is relatively heavy, it is extremely inconvenient to operate when installing, replacing and repairing the distribution valve body, which is easy to collide and damage the friction circle, and the screw adjustment is difficult, which affects the maintenance time and maintenance cost.
